Public tax returns filed by the GWPF’s US-fundraising arm, American Friends of the GWPF, show the organisation received $177,001 in grants and gifts in 2017 (worth approximately £137,900 at the time of writing). That includes a single $124,884 donation (worth approximately £97,265), according to the documents.

The 2017 donations were a significant increase on the amount the GWPF received in 2016 — $128,016 (approximately £99,735).

US tax regulations only require the organisation to declare how much it has received in grants, without disclosing the source of the donations.

GWPF founder, chairman, and former UK chancellor Nigel Lawson is listed as Chairman of the American Friends of the GWPF. The GWPF’s Director Benny Peiser is listed as Secretary. Both spend approximately three hours per week working for the US organisation, the documents declare. Neither were paid for this work, according to the filing.

Major US Republican donor David Herro is listed as the group’s Treasurer, and apparently spends about five hours per week working for the group.

One week prior to the FT’s article being published, Herro donated to the Heartland Institute’s appeal to fund its trip to the Paris climate conference in December of that year. Herro has also donated to the Cato Institute, another U.S. climate science denying think tank.

The Cato Institute is a key organisation in a transatlantic web of lobby groups pushing for environmental deregulation post-Brexit.

DeSmog UK recently revealed how this network of US libertarian campaign groups with links to fossil fuel magnates the Koch brothers and data analytics guru Robert Mercer increased their European and UK activities around the time of the Brexit referendum.

"Fossil-fuel companies have spent millions funding anti-global-warming think tanks, purposely creating a climate of doubt around the science. DeSmogBlog is the antidote to that obfuscation." ~ BRYAN WALSH, TIME MAGAZINE
